You can lock your Chase credit card in about 30 seconds using the Chase Mobile app. Locking temporarily freezes new transactions while keeping your account open and your card number intact, making it ideal when you’ve misplaced your card or spotted a charge you don’t recognize. Here’s exactly how to do it and what happens when you flip the switch.
How to Lock Your Card in the Chase App
The Chase Mobile app is the fastest way to lock your credit card. Follow these three steps:
- Sign in and select your card. From the main screen, tap the credit card you want to lock.
- Find the lock feature. Swipe up to Account Services and tap “Lock & unlock card.”
- Toggle the lock on. Tap the toggle switch to change the card’s status to locked. The change takes effect immediately.
When you’re ready to use the card again, follow the same steps and flip the toggle back. Your card works right away with no waiting period.
What Gets Blocked and What Doesn’t
Locking your card blocks three types of new activity: purchases, cash advances, and balance transfers. If someone tries to use your physical card at a store or enter your number online for a new transaction, it will be declined on the spot.
However, several things continue to work normally even while your card is locked:
- Recurring payments. Subscriptions, utility bills, gym memberships, streaming services, and any other automatic charges you’ve already set up will still process on schedule.
- Digital wallet purchases. If your Chase card is loaded into Apple Pay, Google Pay, or another digital wallet, those transactions can still go through.
- Credits and refunds. Merchants can still post refunds or credits to your locked card.
- Fees and interest. Any account fees or interest charges continue to accrue and post as usual.
This means locking your card won’t accidentally cause a missed payment on your electric bill or cancel your Netflix subscription. But it also means a digital wallet transaction could still go through if someone has your card stored that way.
When Locking Makes Sense
The lock feature is designed for temporary situations. The most common scenario is a misplaced card. You think it might be in your coat pocket, under a couch cushion, or left at a restaurant, but you’re not sure. Locking it buys you time to search without the risk of someone else using it in the meantime.
It’s also useful if you notice an unfamiliar charge and want to freeze everything while you investigate, or if you simply want to prevent yourself from using a particular card for a while. Because locking is instant and reversible, there’s no downside to being cautious.
Locking vs. Reporting Lost or Stolen
Locking and reporting are two very different actions, and choosing the wrong one can create unnecessary hassle.
When you lock your card, your card number stays the same. Nothing about your account changes permanently. You can unlock it at any time and pick up right where you left off. Think of it as a pause button.
When you report a card lost or stolen, Chase cancels the card entirely and issues a replacement with a new card number. That means every merchant where you have your card saved for automatic payments will need to be updated with the new number. This is the right move when you’re confident the card is gone for good or you’ve confirmed fraudulent charges, but it’s overkill for a card that might just be sitting in yesterday’s pants.
Start with locking. If the card turns up, you unlock it and move on. If it doesn’t, you can escalate to reporting it lost or stolen and requesting a replacement at that point.
Cards Linked to the Same Number
If you have multiple physical cards tied to the same card number, locking one locks them all simultaneously. This is worth knowing if you and a family member carry cards on the same account with matching numbers. On business credit card accounts, each cardholder typically has a unique card number, so locking yours won’t affect other cardholders on the account.
What to Do If You Can’t Use the App
If you don’t have access to the Chase Mobile app, you can call the number on the back of your card (or 1-800-432-3117 for personal credit cards) to request a temporary lock or to report the card lost or stolen. A representative can place the hold on your account over the phone. You can also sign in to chase.com on a desktop browser and look for the lock option within your card’s account details page.
